Professional PowerPoint Template Redesign

I have an existing presentation that needs to be redesigned in a modern, unified PowerPoint template.
The current version was created in Canva, but each text line is separated, making it very hard to edit.

I need a designer to:
• Create a consistent and elegant PowerPoint template (colors, layout, and typography).
• Use a unified professional font throughout all slides.
• Keep all the original text exactly as it is, but improve its formatting, alignment, and readability.
• Make sure each slide is easy to edit later (no broken text boxes or line-by-line text).
• Apply a creative and clean design style — not too plain, but not overdecorated.

Deliverable: Editable PowerPoint (.pptx) file with a consistent, polished design.
